Might I ask where you bought the Apollo11 x C99?
While I have not grown the cross, I have grown both C99 and Apollo 11--Joey Weed seeds. Both C99 and Apollo11 had a fast flowering time, about 7 weeks. The high on both was an up energetic high. Both are easy to grow and great yielders. The C99 cloned easily If the cross has the best of both strains, I would say that you will probably be very pleased.
